I have a slightly used HK MR556 upper that had a barrel chop to 10.4” (heavy barrel, not the newer lightweight version), 10” non-vented gas block, HK 416 9” rail, and Knights Armament M4QD compensator.
Parts are as follows (all HK/KAC):
- Complete factory HK MR556 upper with heavy barrel (chopped to 10.4”/MR tab removed)
- MR556 BCG & Charging Handle
- Knights Armament M4QD compensator, for use with KAC NT4
- Gas block replaced with genuine HK 10” non-vented gas block
- Genuine HK 9” 416 picatinny rail
All parts are HK, no Brownells parts.
Less than 200 rds on barrel/BCG. Upper shoots flawlessly suppressed/unsuppressed w/ H3 buffer.
$1799 Shipped/insured CONUS where legal
PP F&F
Only trades (+/- cash based on market value):
- Kahles 318
- MK5 3-18 illum, Mils
- Nightforce ATACR 4-16 or 4-20 MIL/FFP
- Aimpoint T2 in good shape
